Fan Mounting Location (STEP 2)

The DEDPV-705 can be mounted a minimum of 5 linear feet, maximum linear 40 ft, down-stream of the dryer outlet connection. If the DEDPV is installed less than 15 ft downstream of the dryer exhaust, a secondary lint trap is required to be installed between the dryer and DEDPV. Beyond 15ft, a secondary lint trap is considered optional but recommended for extending routine maintenance intervals.

Mounting the Fan (STEP 3)

• A mounting bracket and hardware pack is included and should be used to rigidly mount the fan to a wall stud, rafter, or joist.
• Electrical box must be mounted in the vertical plane for correct pressure sensing

Important: If mounted horizontally, a 1/8 inch weep hole may need to be drilled in the bottom of the fan in order to prevent water from accumulating at the lowest point.

• Hold the mounting bracket against the surface it is to be mounted.
• Mark the location of the two most useful key slots and remove the bracket. Using the provided ¾” long wood screws, attach screws into the structure leaving 1/8” space between the screw head and mounting surface.
• Using the provided self-tapping screws, attach the bracket to the fan as shown.
• Holding the new assembled fan and bracket, align the key slots with the mounting screws and lock them into place.

Duct Installation (STEP 4)

• Leave adjoining dryer duct a minimum of 10-1/8” away from fan inlet and outlet. Install the 10” long cleanout duct using the FC4 duct clamps. See dimensional data below.

Pressure Switch Connection (STEP 5)

Do not connect the tubing in such a manner as to allow condensation from the duct to collect in the tubing
Drill a 3/8 inch diameter hole in the duct wall 6 to 8-inches from the inlet of the fan. Carefully insert the grommet into the hole.
Drilling into a metal duct may produce sharp burrs. Needle nose pliers can be used to remove or flatten sharp edges.

• Attach one end of the clear pressure tubing to the pressure sensor located on the electrical box.
• Mark the opposite end of the pressure tubing ½ inch from the edge and insert into the grommet until the marking is reached.

Indicator Panel (STEP 6)

The DEDPV-705 is equipped with a remote mount, low voltage, operation indicator panel. This wall-mounted indicator panel contains a blue LED that is intended to visually alert the occupant of any detected faults. The panel must be mounted in a 2 gang decora switch plate with a warning label (decora plate and label provided). paragraph C for the required mounting location.

Connecting Indicator Panel (STEP 7)

• Connect the end of the 50-foot cable that has a mating two-position connector to the receptacle located on the dryer booster fan control box.

SEQUENCE OF OPERATION

1. Apply power to the DEDPV-705
   • The blue light on the indicator panel only illuminates when the DEDPV-705 is operating.
2. The DEDPV-705 turns ON approximately 10 seconds after the dryer has started by sensing the pressure inside the exhaust duct. A blue LED will illuminate (solid) on the indicator panel when the DEDPV is operating.
3. Once ON, the DEDPV-705 will run continuously for 5 minutes.
4. After 5 minutes, the fan will temporarily turn off to verify the status of the dryer. If the dryer is still running and positive pressure is sensed within the exhaust duct, the DEDPV-705 will re-energize and run another 5-minute cycle. The indicator panel will remain lit during this verification step.
   • The verification check takes approximately 30 seconds.
5. If after a complete 5 minute run cycle the DEDPV does not sense pressure from the dryer, the DEDPV-705 will engage in a final 5-minute cool-down cycle before turning OFF.

RECOMMENDED MAINTENANCE

Since fan bearings are sealed and provided with an internal lubricating material, no additional lubrication is necessary. Fan impeller may accumulate lint. Periodic inspection, based upon dryer usage, should be performed to ensure that the fan impeller is not obstructed or loaded with lint. Under normal conditions, fan should be inspected a minimum once a year.

Excessive noise or vibration may be an indication of lint buildup on the impeller

To inspect and clean the impeller

• Disconnect the incoming power supply at the source.
• Loosen the 4 fast clamps and remove the 10-inch extender ducts from the fan inlet and outlet; remove any lint buildup on the impeller and near the outlet.
• Reconnect the duct to the fan. Turn power supply on.

TROUBLESHOOTING

No Indicator Light:  DEDPV not operating when dryer runs

• Check that the pressure tube is free of moisture, cracks, and properly inserted into the exhaust duct upstream of the fan.
• Solution: The DEDPV-705 is interlocked to the dryer by sensing the pressure inside the exhaust duct when the dryer turns on. Replace the tubing if damage is observed
• Verify that the low voltage wiring is properly plugged into the DEDPV-705.
• Solution: The Indicator LED is polarity sensitive. Check that the RED wire is connected to the positive terminal and the BLACK wire is connected to the negative terminal.
• The DEDPV-705 has a non-resettable thermal fuse link which will trigger when exhaust temperatures exceed 196°F. This is a safety feature designed to prevent the DEDPV from operating during abnormal/dangerous drying conditions. Call Technical Support for authorization before opening the electrical compartment; check resistance across the thermal overload protector.
• Solution: Dryers are equipped with operating temperature controls that monitor drying temperatures. Normal exhaust temperatures should not exceed 167°F. If the safety thermal fuse in the DEDPV-705 trips, the dryer is operating outside its limits. Contact the dryer manufacture and replace the DEDPV-705.

Single Flash:  DEDPV fan wheel is locked or rotation not detected

• Remove DEDPV and check for lint or debris that may have accumulated at both the inlet and outlet side of DEDPV-705. A double flash would most likely be a pre-curser to the symptom.
• Solution: Routine maintenance on all dryer exhaust systems are necessary to ensure lint is not accumulating and creating blockages.
• A hall effect sensor integral to the motor is used to sense the rotation of the fan wheel. A loose connection within the fan electrical box can cause the system to think there is no rotation.
• Solution: Call Technical Support for authorization to open the electrical box and check connection (H1, H2, H3).
• Double Flash:  DEDPV abnormal operation; less than standard speed
• If lint or debris is accumulating near the inlet of the motor wheel there may be a reduction in detected RPM. This could be an indicator that maintenance is required.
• Solution: Loosen the 4 fast clamps and remove the extender tubes. Cleanout all debris and lint from both inlet and outlet side of the fan.

Triple Flash:  Low Airflow (Restrictive)

• Only available on models identified as 46005 & 46006.
• As the pressure inside the exhaust duct increase, the fan speed inherently also increases. Building codes require a minimum air velocity of 1200 ft/min; limits have been put in place to alert the occupant when the exhaust system is performing below this requirement.
• Solution: On existing systems, if this is the first time such an indicator is observed, have the exhaust system inspected and cleaned from dryer to the exterior termination. This is an indicator that a blockage is forming either upstream or downstream of the DEDPV- 705.
• Solution: On new construction, this may be an indicator that the overall exhaust duct layout is too restrictive. Review STEP 1 of the installation manual to ensure duct length has been calculated properly.
• If the flashing occurs ONLY during the DEDPV-705 final 5 minute cool down cycle, there is no safety concern
